The verdict in three sentences
As soon as your application processes personal health data, hosting must be HDS-certified: budget 300 to 1,500 EUR/month in 2026 depending on volume, redundancy and support level. The premium over standard hosting (20-150 EUR/month) is explained by encryption, access traceability, qualified backup and the HDS contract. Compliance takes 4 to 8 weeks; skipping it exposes you to GDPR sanctions and closes access to hospital and insurer contracts.
What HDS hosting costs in 2026
Price depends mostly on data volume, redundancy level and availability commitments. Here are the 2026 orders of magnitude.
| Application profile | Volume / traffic | Monthly HDS cost (est. 2026) |
|---|---|---|
| MVP / pilot | < 1,000 patients | 300 - 500 EUR |
| Growing application | 1,000 - 10,000 patients | 500 - 900 EUR |
| Established platform | 10,000 - 50,000 patients | 900 - 1,300 EUR |
| Multi-facility | > 50,000 patients | 1,300 - 1,500 EUR+ |
| High-availability option (99.9 %) | Multi-zone redundancy | +30 to +50 % |
To this add an initial compliance setup (audit, encryption, logging, HDS contract) typically billed 3,000 to 12,000 EUR once, depending on application complexity.
The HDS premium versus standard hosting
Many software vendors underestimate the gap. The table below compares at equivalent scope.
| Item | Standard hosting | HDS hosting |
|---|---|---|
| Monthly cost | 20 - 150 EUR | 300 - 1,500 EUR |
| Encryption at rest | Optional | Mandatory |
| Access traceability | Basic | Full audit log |
| Backup | Standard | Qualified, tested |
| Contract / liability | Generic | Dedicated HDS contract |
| Health-market eligibility | No | Yes |
| Legal risk | High | Controlled |
The gap costs money, but it conditions access to serious clients (hospitals, clinics, insurers) and protects you in case of audit or incident.

Mini case study
Julien, CTO of an e-health startup in Nantes, hosts his chronic-patient monitoring app on a standard server at 90 EUR/month. A hospital tender worth 60,000 EUR/year requires HDS hosting.
He moves to HDS hosting at 700 EUR/month (i.e. 8,400 EUR/year) and commits 7,000 EUR to compliance. The total premium in year one is about 14,700 EUR. By winning the 60,000 EUR/year contract, the return is immediate: compliance is not a cost, it is the condition of access to revenue four times the premium.
FAQ
Am I required to use HDS hosting? Yes, whenever you host personal health data on behalf of third parties. Failing to do so exposes you to sanctions and excludes your solution from health-sector contracts.
What's the difference between HDS and plain GDPR? GDPR applies to all personal data; HDS is an additional requirement specific to health data, with host certification, encryption and reinforced traceability.
How long to become compliant? Budget 4 to 8 weeks: audit, encryption, access logging, migration to a certified host and signing the HDS contract.
Is the premium worth it? For any solution targeting hospitals, clinics or insurers, yes: compliance is a commercial prerequisite. A premium of a few hundred euros/month unlocks contracts worth tens of thousands.
Can I start standard then migrate? Technically yes for a pilot without real patient data, but from the first real patient you must be HDS. It's better to plan the architecture from the start.
